Chemistry of Carbohydrates

94.1K
Carbohydrates are an essential part of the diet in humans and animals. Grains, fruits, and vegetables are natural sources of carbohydrates that provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. The stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule represents carbohydrates. In other words, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. This...

Production of Organic Acids

82
Lactic acid, an important organic acid extensively applied in food, pharmaceutical, and biodegradable polymer industries, is primarily produced via microbial fermentation. This method is favored over chemical synthesis due to its environmental sustainability and capacity for enantiomerically pure product formation. Among various microbial processes, the fermentation of starch-based substrates stands out due to the abundance and renewability of raw materials like corn and potatoes.Hydrolysis of...

Oligosaccharide Assembly01:24

Oligosaccharide Assembly

3.9K
Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.
Multiple sugar molecules that may or may...

Area of Science:

  • Carbohydrate Chemistry
  • Biochemistry

Background:

  • Amylose (AM) is a crucial component of starch with significant applications.
  • Efficient and controlled isolation of AM is essential for research and industry.

Purpose of the Study:

  • To delineate and compare three primary in vitro methods for obtaining amylose.
  • To identify factors influencing amylose yield, purity, and degree of polymerization (DP).

Main Methods:

  • Enzymatic synthesis using α-d-glucose-1-phosphate (G1P) and phosphorylase.
  • Amylose leaching by heating starch suspensions above gelatinization temperature.
  • Amylose complexation via selective precipitation using agents like n-butanol.

Main Results:

  • Enzymatic synthesis yields low polydispersity AM with controllable DP.
  • Starch leaching allows large-scale AM isolation, with purity dependent on temperature and processing.
  • Complexation requires complete starch dispersion for high-purity AM separation.

Conclusions:

  • Each method (enzymatic synthesis, leaching, complexation) offers distinct advantages for amylose isolation.
  • Process parameters significantly impact amylose characteristics, including DP and purity.
  • Further enzymatic modification can tailor high-DP amylose into lower-DP fractions.
